“Looks like somebody knocked him cold! It isn’t the cop that was with us. Wonder where he came from?”

The officer came to life as they propped him against the wall. He looked at both men in a daze.

“Where’s the guy?” he questioned.

“Who do you mean?”

The policeman rubbed his head as he looked upward at the second floor of Doc Birch’s house. He pointed as he spoke.

“Heard a racket up there,” he explained. “Fellow was coming out the window when I got here. Landed on my neck before I could pull my gun. Took my coat and my gun while I was woozy. Then I took a swing at him. Boy, what a wallop he handed me!”

His hand went to his jaw.

“Right here,” he added.

The two secret service men looked at one another. Their looks registered amazement; then changed to anger.

“It was him!” exclaimed one. “Rigged up like a cop! Grabbed this fellow’s coat and hat. He fooled us!”
